Abstract

The Duel Mass Flywheel (DMF) is primarily used for damping of oscillations in automotive power trains and to prevent gearbox rattling. We explain the DMF machines along with its applications and components. Afterwards a detailed initial model of the DMF dynamics is presented. This mainly includes a model for two stage arc spring in the DMF and their behavior. Both centrifugal effects and redirection forces act radially on the arc spring which induces friction. An experimental DMF model is compared to a measurement to model validation. Finally the observability of the engine torque using the DMF is discussed. For this purpose the DMF is manufactured and done experiment or testing to see the result. And then results are compared with the conventional flywheel. The objective when developing the DMF was therefore to isolate the tensional vibration from the drive train as much as possible caused by the engine’s rotating mass. Owing to its internal damping spring the DMF almost entirely absorbs these tensional vibrations. The result is very good vibration damping. Flywheel inertia is stored when you rev the engine slightly before letting the clutch out -this small amount of extra power helps in getting the motorcycle with minimum effort. By "borrowing" the power for a few seconds engine has to develop less to move from the standing start. Once the clutch is completely engaged, inertia can no longer be borrowed the motorcycle can only be used what it products in "real time".
